Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of TNC price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: February 26, 2024
End date: April 29, 2025
a = 6.1031
b = -0.0010
s = 0.0485
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -29.93%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0485) – 1
= 21.43%

Top border of price channel:
Exp(Y961)
= Exp(a + b × X961 + 2 × s)
= Exp(a + b × 1,397 + 2 × s)
= Exp(6.1031 + -0.0010 × 1,397 + 2 × 0.0485)
= Exp(4.8390)
= $126.34
Bottom border of price channel:
Exp(Y961)
= Exp(a + b × X961 – 2 × s)
= Exp(a + b × 1,397 – 2 × s)
= Exp(6.1031 + -0.0010 × 1,397 – 2 × 0.0485)
= Exp(4.6448)
= $104.04

= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(6.1031 + -0.0010 × 1,825 + 2 × 0.0485)
= Exp(4.4219)
= $83.26
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(6.1031 + -0.0010 × 1,825 – 2 × 0.0485)
= Exp(4.2277)
= $68.56
